To provide a paper feeding device and an image forming device preventing deterioration of separating performance with a simple structure.

A link mechanism comprised of a first link 5 and a second link 6 functions to maintain an intermediate plate 10 swinging around a pivot 10a and an arm 4 provided with a claw 2 roughly in parallel. Consequently angles of the claw 2 pressed against a sheet bundle 61 interlocks with the arm 4, namely interlocks with the intermediate plate 10 to maintain angles between the claw 2 and a surface of the sheet bundle 61 always fixed.
